In the Minotaur Ruins, every chest my PC opened had at least a Banded Mail item (some chests other items as well). But each chest, this same normal Banded Mail.

I thought it weird but meh, until...then I had an encounter with 2 Minotaurs, and both of them dropped the same +1 EB vs. Chaotic quarterstaff. Coincidence? Highly unlikely at this point.

So, maybe it was a funny day for the Loot System or what, but still weird that exact similar items would drop one after another, and that all the chests would contain the exact same item (but/and sometimes other non-similar items).
